Blind-Deaf-Mute

Blind-Deaf-Mute runs as a social party game for servers with exactly three players online. Every ten minutes a roulette picks one of the three to be blind, one to be deaf and one to be mute. Each player receives the new role in a chat message and in the action bar when the roulette spins, and no player gets the same role twice in a row. Outside the roulette the roles stay paused.

The blind role reuses Minecraft's own blur shader, the one behind the pause menu, and applies it continuously at a stronger setting. The screen stays darkened and blurred over the world, the HUD and the inventory, so the player cannot make out anything clearly. The deaf role muffles the voice of every other player, who sounds as if heard through a wall. The mute role broadcasts the player's voice muffled to others, whatever is said.

The deaf and mute effects work by intercepting voice audio on the server through the plugin API of Simple Voice Chat, applying a low-pass filter and a volume reduction. The voice chat mod itself is not modified. Blind-Deaf-Mute requires Fabric API and Simple Voice Chat, and both the server and each connecting player must run it alongside Simple Voice Chat. It runs on Minecraft 1.21.8 with Fabric Loader. Files are published only for Fabric, for 1.21.8, under the MIT License, and the project is not open source.
